CLIP MACHINE.

Application filed July 22, 1927. Serial No. 207,782. I

This invention relates to devices by which clips can be made and bent to fit around different parts of ornamental iron, as the clips around ornaments attached to posts or other bars in balustrades.

One of the objects of this invention is 'to simplify the making and fitting of clips in the ornamental iron industry. I i

Another object is to provide a device by which clips can be cut to length from the full bar and at the same time bent to any desired shape preparatory to being clinched around bars and ornaments, such as in balustrades.

Another object. is to provide adjusting means for the cutting to allow a cutting to different lengths to suit various requirements.

Another object is to provide adjusting means for stopping off the length of the bars to assure desired variations in the length of clips. j V

Another object is to provide a mechanism by which a plain piece of round steel may be used asthe die-part of the mechanism.

Another object is to provide means by which a finished clip is automatically ejected from the device. V I

Other objects will appear from the following description and appended claims as well as from the accompanying drawing, in which Fig. 1 is a fragmentary front elevation of a cutting and bending machine, partly in section to illustrate the proper relation of the cooperating parts in the device in a simple form arranged according to this invention.

Fig. 2 is a cross section on line 22 of Fig. 1.

Fig. 3 is a side elevation of a clip in a plain form commonly used to hold different parts together in the ornamental iron industry.

Fig. 4 is a fragmentary side elevation, in which a clip is illustrated in proper relation to an upright and ornaments as used, for in stance, in balustrades.,. j

Fig. 5 is a cross section on line 5-5 of Fig. 4. r V

Fig. 6 is a side elevation of the pivotally connected portion of the main frame, slight- 1y modified to hold a square die instead of a round die illustrated inFigs. 1 and 2.

. Fig. 7 is. a midsectional view of Fig. 6 illustrating a finished clip in position around the die.

Clips are used for many purposes to reduce lablor in assembling structures of light mate Ila. I

.For instance, inthe'ornamental iron indus- 7 try t 1s quite common that ornamcnts'are merely clipped tothe posts, or rails, or other parts of a balustrade by clips of this sort illust-rated in Figs. 4 and 5, in which 6 designates a portion of a post or upright of a balustrade, and 7 and 8 indicate portions or or naments clinched and held to the post 6 by a clip 9. The cross section in Fig. 5 shows how the clip 9 is bent and clinched around the post and the ornaments. i l

Fig. 3 illustrates a. clip in half-finished condition, in which form it is commonly made preparatory to being used in a manner asillustrated in Fig. t and Fig.5,

Clips of this form as illustrated in'Fig. 3 may be bought on the open market, though it must be understood that the ornamental iron worker must pay the .manufacturei"s profit on the half-finished clip and eventhen is compelled to accept an article that is not fully purpose for which itmay.

satisfactory for the have to be used. 7 v

In Fig. 5, for instance, asmall space is indicated at 10, which may easily result with partly finished clips bought on the openmarket by an ornamental iron worker.

On the other hand, it may happen that the ornamental iron worker has to chip or file off the ends of the clips to avoid an overlapping of the ends of .clips when he comes to use ready bought clips for a certain class of work assembled in his shop.-

Theinventiondisclosed herewith has therefore for its principal purpose to supply the ornamental iron worker or smallshopman with a small and reasonably priced device by which he is enabled to make his own clips to absolutely fit in his particular line of work, though, of course, this machine may also be used to furnish clips of various and very accurately proportioned forms to other manufacturers.

Asillustrated, the (levice consists mainly of a frame 11 with another major portion 12 pivotally connected to the frame as indicated at 13. r q

The frame portion 11 maybe mounted in a vise or on a bench and the pivotally connected member 12 may be operated by hand by means of the lever 14 or by other secondary mechanisms not particularly illustrated but commonly used with such devices and machines. i

The frame portion isprovided a jaw member 15 integrallyformed on the base.

member, and a second jaw member 16 adj ustably mounted on the base member to be adjusted in suitable relation to the first-named jaw member, leaving a space between the opposing faces 17 and 18. V

The movable portion- 12 of the device 1s provided with a comparatively large cutout 19, embodying in its front-end cylindrical. faces to receive and hold a round block 21' to form the die of the device.

From the illustrations in Figs. 3, 4 and 5 it will be clear that the space between the opposite faces 22 and 23,indicated in Fig. 3, of the clip 9 must accurately correspond tothe combined thicknesses of the materials tobe held between these opposite faces within the clip, as illustrated in Figs. 1 and 5.

The die must therefore be of a thickness to fit between the opposite faces 22 and 28 of the clip 9 illustrated in Fig. 3.

To facilitate an accurate bending of a clip, various dies must be provided in a machine of this type.

To simplify die work, the whole machine is designed so that a plain round bar may be used as a die, sothat any person who uses this'machine can make his own die by merely cutting off a piece from a round steel-bar to a length corresponding to the space required between the opposite shanks of a clip.

It will be understood that it is an easy mattor for anyone to cut off and slightly grind the ends of the cutoff piece of a round bar to form such a die.

The opposite faces 17 and 18 of the jaw in the base member 11 are then merely set to leave a space at 2 1 and to correspond to the exact thickness of a required clip. A

die 21 may for this purpose beset first by the set screw 26 to leave the exact required space between the die 21 and the jaw 15, and then the movable jaw 16 can be moved to leave the exact required space between the adjusting die 21 and the face 18 olthe jaw 16 Cutting knives 27 and 28 are provided by which a suitable piece of a bar for a clip can be cut oil to a proper length, preparatory to 7 being clinched or bent between the die 21 and the jaws 1'5 and 16'.

The cutting knife 27 is adjustably mounted on the base 11 and the cutting knife 28 is adjustably mounted on the pivotally connected major portion 12.

When the knives are so set, the length of one shank is established between the cutting knives and the die 21. The length of the other shank of a clip is provided by a stop-plate 29, adjustably secured as indicated at 30.

On each movement of the major portion 12 by the handle member 14, a clip can then be cut to length and clinched or bent in one movement of the device.

Inasmuch as a finished clip tends to stick to the die 21, automatic ejecting means are provided on the device.

A lever 31 is pivotally mounted at 32 on the main frame, connected by a link 33 to the lever 14 and also connected to an ejecting tongue 3 1 extending to a point between the 'die 21 and the jaws l5 and 16.

On each downward or clip-forming move ment of the machine the ejector is automatieally withdrawn from the position in which it is indicated in Fig. 2, while on each opening movement of the machine the ejector automatically moves between the die and the jaws 15 and 16, adapted to eject the finished clip from its position in the machine.

A guide is provided near the cutting knives by which a bar may be fed through the cutting knives until it abuts against the stop 29 and after each movement of the machine the bar can again be pushed against the stop 29 as soon as the finished clip has been ejected from the machine. The guide 35 serves therefore to quickly bring the nec essary material into proper position between the cutting knives of the device and between the clip-forming jaws.

The slightly modified form illustrated in Figs. 6 and 7 makes it clear that the die can be made and cut off from any bar-steel.

Though the above specification with reference to the illustrations in Figs. 1 and 2 discloses the most advantageous form of die cut from a round bar, it must be understood that a short piece ofsteel may be cut from any bar to provide the required thickness of die, whether the bar is of round, square, or any otherform of steel.

The principal feature is that the simple cutting oil from the. end of a bar will provide a finished die ready for use. i

The illustrations in Figs. 6 and 7 are therefore for the purpose to show that other than round steel bars or other than round dies may be used in this machine;

The die illustrated in Figs. 6 and 7 may be said to have been cut from a bar of square cross section. The die 21 of this square cross section requires merely a setting oil or shouldering in the member 12, as indicated at 36.

I, therefore, do not limit myself to the round die but may use any die cut from a steel-bar to quickly furnish a die ready for use as described above.

Having thus described my invention, I claim:

1. In a clip making machine, a main structure consisting of two pivotally connected portions adapted to move in a manner of shears, cutting blades ustably mounted on the said pivotally connected portions for shearing purposes, jaws provided on one of said portions sidewise of said blades, a die adjustably mounted'on the other of the said portions opposite the said jaw, and a stop sidewise of the jaws adapted to be spaced the same distance from one side of the jaw to correspond to the distance at which said blades may be set in relation to the other side of the jaws.
